The flowers are found at the base of the bract and are usually green-white. The inflorescence is single to few-flowered, bracteate and usually forming a congested raceme the bracts are leaf-like or broader and often coloured or patterned, the inner bracts are successively smaller. They have a soft leathery texture and the margins are sometimes crisped and smooth or ciliolate or bristly. Leaves are few to several, and scattered along the stem or, in the stemless species, congested and often prostrate, ovate to linear-lanceolate, clasping below, parallel-veined, often with a distinct midrib when broad, the leaves are arching. It has a fan-like, basal fold, and is covered with dark leathery to woody tunics. All species have an ovoid corm (a corm unlike a bulb, is a stem that is swollen and modified for storage, flattened on top and slightly concave on the bottom: when upon being cut, the corm appears solid). Species of the genus Colchicum are short-stemmed or stemless reaching a the height of 150 mm. images at PlantSystematics.The name is derived from the Greek word, kolkhikon, referring to Colchis, an ancient region east of the Black Sea.The families of flowering plants: descriptions, illustrations, identification, information retrieval.

This is supported by molecular phylogenetic studies with dense species sampling (i.e. The former controversy regarding the inclusion of Androcymbium in Colchicum has now been resolved in favor of the 2007 classification of Manning et al. ![]() ![]() is excluded from this family and placed in its own family Petermanniaceae, Liliales. (including Androcymbium Willd., Bulbocodium L. (including Neodregea C.H.Wright and Onixotis Raf.) (excluding the North American species to the genus Prosartes D.Don, now in the family Liliaceae, Liliales) The phylogenetic classification of Vinnersten & Manning circumscribes the family as follows: The Dahlgren system and the Thorne system (1992) also recognized this family, and placed it in order Liliales in superorder Lilianae in subclass Liliidae (monocotyledons) of class Magnoliopsida (angiosperms). It is a group of herbaceous perennials with rhizomes or corms. ![]() The APG III system, of 2009 (unchanged from the APG systems, of 19), recognizes this family and places it in the order Liliales, in the clade monocots. The family is characterized by the presence of colchicine. Family of monocot flowering plants, in order LilialesĬolchicaceae is a family of flowering plants that includes 15 genera with a total of about 285 known species according to Christenhusz and Byng in 2016.
